30 60 90 right triangle
so
ratio of short leg : long leg : hypo = a : a√3 : 2a
if short leg = 10
long leg = 10√3 and hypo = 2 x 10 = 20
so a = 10√3, c + d = 20
also small triangle on right is 30 60 90 right triangle
hypo = 10, short leg d = 5 and long leg b = 5√3
if d = 5 then c = 20 - 5 = 15
answer
a = 10√3
b = 5√3
c = 15
d = 5
Answer:
D. The clinic opened at 7:30 A.M. and closed at 6:30 P.M.
Step-by-step explanation:
Pay attention to the times, and the amount of time the given location is open.
Only option D makes sense since the clinic open for 11 hours and the difference from the times given is exactly 11 hours; the other options are off, some give longer, and some give fewer amount of time.
Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
Answer:
$69.75
Step-by-step explanation:
Multiply $2.25 by 31 students
1sec = 3.6 x 10^5gallons
1 hr = 3600 x 3.6 x 10^5gallons
1hr = 1.296 x 10^9 gallons
